Abstract This study was carried out during two seasons of 2015/2016 and 2016/2017 to study the effect of three nitrogen leves and four varieties of stevia on growth, yield and its components as well as chemical analysis of stevia . The results showed that,varieties they differed response to growing.China1 varietal gave the highest values of chemical characters in all cuts studied . Egy1 varietal gave the highest values of yield composition characters in all the three cuts studied . The effect of interaction between nitrogen fertilizer levels and stevia varieties on growth character, yield and chemical characters values, nitrogen fertilizer level of 40 kg N/ fed/cut applied to Egy1 varietal gave the highest values of yield composition characters in all the three cuts studied in both seasons. While nitrogen rate of 40 kg N /fed /cut and China1 varietal gave the highest values of chemical characters in all cuts studied. |
